It's actually quite simple. You'd better have a snack and a drink before you go. One is that both of them are easy to let go after drinking and have weak self-control. One is to get drunk even if something happens to avoid embarrassment. After drinking a little wine, find an opportunity, such as walking beside her and pretending to trip, and then she will give you a hand and put her arms around you. Next thing you know, it's on.
